n.

A measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14.

pH

n

(Chemistry) potential of hydrogen; a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution. Pure water has a pH of 7, acid solutions have a pH less than 7, and alkaline solutions a pH greater than 7

pH

(pē′āch′)

A numerical measure of the acidity or alkalinity of a solution, usually measured on a scale of 0 to 14. Neutral solutions have a pH of 7, acidic solutions have a pH lower than 7, and alkaline solutions have a pH higher than 7.

pH

A scale which gives a measure of the acidity of an aqueous solution. A neutral solution has a pH of 7; an acidic solution has a lower value, and an alkaline solution a higher value.

pH - (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic);

Chlorine in tap water can affect vulnerable plants, and in hard water areas you'll see excess calcium building in rings around pot bottoms, DAVID ASK GARDENING QUESTIONS ANSWERED which, over time can change the pH balance of the soil.

Dry, flaky, red, and itchy skin is all too common during the winter months, as the combination of dry indoor heat and harsh outdoor air disrupts the natural pH balance, explains Marnie Nussbaum, a board certified dermatologist and chief medical spokesperson for Sebamed.
